dc.description.abstract高温合金以其优异的高温强度、表面稳定性及耐高温、耐腐蚀等性能被广泛应用于航空航天、冶金和机械等领域。Co、W、Nb、Cr元素作为高温合金中重要的基体和合金化元素被广泛加入各类高温合金中以获得优越的性能。然而到目前为止,合金化及强化机制对合金性能的影响还没有系统的研究。相图作为材料设计中不可或缺的工具蕴含了丰富的组元之间的物理、化学相互作用信息,被称为材料设计的地图,是合金成分和结构设计的理论基础。因此,本研究采用合金法实验测定了Co-W-Nb-Cr四元系中Co-W-Nb、Co-W-Cr、Co-Cr-Nb及Cr-W-Nb四个三元系在不同温度时全成分范围内的相平衡。其主要研究工作如下: (1)实...
dc.description.abstractThe superalloys are extensively applied in aerospace, metallurgy and mechanical industry because of their fantastic properties, such as remarkable high-temperature strength and surface stability, high operating temperature, good corrosion resistance and so on. Co, W, Nb and Cr are widely used as base and alloying elements in many kinds of superalloys to acquire expected properties. However, it is ...
